摘要： Decoding video data. Receive a first video stream including a first plurality of frames encoded at a first resolution, a second video stream including a second plurality of frames encoded at a second resolution and a residual bitstream encoded at a third resolution. The second plurality of frames correspond to the first plurality of frames encoded at the first resolution and the first resolution is greater than the second resolution and the third resolution is at least between the first and second resolutions. Side information determined based at least on the first plurality of frames and the second plurality of frames. The video data decoded based at least on one received frame of the first plurality of frames, at least one received frame of the second plurality of frames encoded at the second resolution, the residual bitstream encoded at the third resolution, and the side information.

摘要： Methods for adapting the sliding window of sliding window-based error correcting codes based on the coding structure of a compressed media stream are disclosed. In one aspect, a sender packetizes each frame of a media stream to be sent to a receiver into a set of frame packets. The sender also determines compression dependence of each frame and adapts a sliding window of a sliding window-based error correcting code based on the compression dependence of the frame. The sender encodes the frame packets into at least one associated parity packet according to the error correcting code with the adapted sliding window, and sends the frame packets and the at least one associated parity packet to the receiver.

摘要： A computer-implemented method for managing upstream bandwidth of a network including changing QoS settings, by a router, of a video device of a plurality of video devices in the network to a higher priority than other of the plurality of video devices. The plurality of video devices concurrently transmit video data. The computer-implemented method further includes estimating an overall upstream bandwidth by the higher priority video device and determining operating rates, by the router, for the plurality of video devices, such that said modem buffer is not backlogged.

摘要： Adapting characteristics of a video stream. A source video stream is received comprising instructions to employ at least one reference frame at a video adaptation device, wherein the source video stream is encoded. The source video stream is adapted, at the video adaptation device, such that the instructions are adapted to store a different number of reference frames. A video stream is produced with the different number of the reference frames.

摘要： Controlling artifacts in video data. Image data of collocated pixels of a plurality of frames of the video data is sampled (310), wherein at least a portion of each of the plurality of frames corresponds to an object that does not move across the plurality of frames. A statistical curve fit is performed (320) on sampled image data of the collocated pixels, wherein the statistical curve fit places less consideration on a sampled collocated pixel that corresponds to movement of an object across the plurality of frames. An adjusted frame is generated (330) based at least in part on at least one parameter of the statistical curve fit.
